f The integrated ATR-FTIR peak areas of the Cu, Sn, Cu6Sn5 with and without calibration. Full size image To produce a pure formic acid solution, we conducted CO2R using an AEM (Sustainion X37-50 Grade) based SSE-MEA electrolyzer. 0.5 M H2SO4 was used as the anolyte and IrOx/...
In-situ point samples of CO2/SO2 ratios using MultiGAS12, or remote sensing gas composition measurement with COSPEC13,14,15,16, or open path FTIR spectrometry (OP-FTIR)17,18 are combined with measurements of SO2 flux using ultraviolet remote sensing19,20. CO2 fluxes may also be determined ...
It was characterized by FTIR and the gas separation performance was analysed by Design of Expert (DOE) method. FTIR result revealed the intensity of peak for sulfone S=O vibration at 1322 cm-1; it was related to O=S=O bound of polysulfone in the sample. The single concentration variable ...
This increased disorder leads to a wider range of bond lengths and bond angles, resulting in a broader FTIR peak. Fig. 5 FTIR spectra of Pb1-xCoxFe12O19 (where x = 0.0, 0.25, 0.75, and 1.0) ferrite nanoparticles Full size image The second band, B(υ2), corresponds to Mocta...
The evolution of the solid-state reactions was studied in situ, using a surface-sensitive multiple internal reflection technique coupled with infrared spectroscopy (FTIR). Subsequent improvement by UV annealing of dielectric layers deposited on InP substrate was demonstrated from C(V) measurement of ...
The presence of transpolyacetylene segments in pGO is also confirmed by the FTIR peak at 1680 cm−1 assigned to C=C stretching frequency (Fig. 3). Another important characterization of GO quality in terms of disorderliness attributed to sp3 in predominantly sp2 hybridization is studied using ...
Fourier transform infrared (FTIR) spectra were measured by using a Nicolet Nexus 470 spectrometer. The Vario Micro Cube elemental analyzer was chosen to perform elemental analysis (C, H and N). TG analysis was carried out on a thermobalance (STA-499C, NETZSCH), where the heating rate was ...
J.W. and A.X. performed the XPS and XRD measurements. J.E.H. performed the Raman spectroscopy measurements. L.K.S. performed the FTIR measurements. T.P. collected the SEM images. X.W., Z.W., Y.X., D.S., A.H.I. and H.J. contributed to data analysis and manuscript editing...
thereby leading to direct access to underlying electron transfer processes. The fourth harmonic components of FTacV obtained on Sb1Cu-5 in CO2-saturated 0.5 M KHCO3showed a well-defined reduction peak at approximately −0.60 V vs. RHE, which was absent in the Ar-saturated electrolyte,...
